Industrial smogs

There are two general types of smog industrial and photochemical. Industrial smog, produced largely from the combustion of coal and oil, is high in particulates. Its main chemical ingredient, however, is sulfur dioxide, which accumulates in the water coating of aerosols and is transformed to sulfuric acid ... 

Industrial smog Visible airborne pollution containing large amounts of particulates and sulfur dioxide and produced largely from the combustion of coal and oil.

Industrial smog Smog generally caused by industrial activity such as coai burning also known as London smog... 

The main ingredient in industrial smog is sulfur dioxide. Laboratory experiments have shown that sulfur dioxide increases aerosol formation, particularly in the presence of mixtures of hydrocarbons and nitrogen oxides. For example, mixtures of 3 parts per million (ppm) hydrocarbons, 1 ppm NOg, and 0.5 ppm SO2 at 50% relative humidity form aerosols that have sulfuric acid (HgSO ) as a major product. Breathing a sulfuric acid aerosol is very harmful, especially to people suffering from respiratory diseases such as asthma or emphysema. At a concentration of 5 ppm for 1 hour, this kind of aerosol can cause constriction of bronchial tubes. A level of 10 ppm for 1 hour can cause severe breathing distress. 

Industrial smog is produced when sulfur is converted to sulfur dioxide during the burning of coal or other sulfur-containing fuels. 

About 100 years ago, a new word entered the English language—smog. It referred to a condihon, common in London, in which a combination of smoke and fog obscured visibility and produced health hazards (including death). These conditions are often associated with heavy industry, and this type of smog is now called industrial smog. 

Industrial smog consists primarily of particles (ash and smoke), S02(g), and H2SO4 mist. A variety of industrial operations produce significant quantities of S02(g), but the main contributors to atmospheric releases of S(32(g) are power plants burning coal or high-sulfur fuel oils. SO2 can oxidize to SO3, especially when the reaction is catalyzed on the surfaces of airborne particles or through reaction with NO2 ... 

The control of industrial smog and acid rain hinges on the removal of sulfur from fuels and the control of S02(g) emissions. Dozens of processes have been proposed for removing SO2 from smokestack gases, one of which is illustrated in Figure 22-16. In this process, S02(g) from the coal reacts with CaO(s) to form deposits of CaS03(s). 

In an atmosphere polluted with industrial smog, Cu corrodes to a basic sulfate, Cu2(0H)2S04. Propose a series of chemical reactions to describe this corrosion. 

The inductive effect refers to the shifting of electron density from one atom toward another through the chain of cr bonds that connects them. Industrial smog is air pollution in which the chief pollutants are S02(g), 503(g), H2SO4 mist, and smoke. 

Smog is the general term used to refer to a condition in which polluted air reduces visibility, causes stinging eyes and breathing difficulties, and produces additional minor and major health problems. (See also industrial smog and photochemical smog.)...
